The calculation of radar cross‐section (RCS) using the TLM method
International Journal of Numerical Modelling: Electronic Networks, Devices and Fields, 1989AbstractThe calculation of the radar cross‐section (RCS) of complex bodies using the symmetrical condensed TLM method is presented. The technique is based on a near‐to‐far field transformation of the TLM calculated near fields. Several two‐dimensional examples are presented which validate the method.

CFD spinoff - Computational electromagnetics for radar cross section(RCS) studies
Flight Simulation Technologies Conference and Exhibit, 1990A finite-volume discretization procedure derived from proven CFD methods is used to solve the conservation form of the time-domain Maxwell's equations, in order to compute EM scattering from layered objects. This time-domain approach handles both single-frequency/continuous wave and broadband-frequency/pulse incident excitation.

Radar cross section (RCS) statistical characterization using weibull distribution
Microwave and Optical Technology Letters, 2013AbstractRadar target's backscatter varies rapidly because of change in the relative position of each scatterer, body vibration while moving and so on. Weibull distribution is adopted as an inclusive description of the envelope of various targets' backscattering in this paper.

Bi-Static Radar Cross Section (RCS) Reduction of Impedance Cylinder
2006 IEEE Conference on Radar, 2006Reduction of RCS of military targets is important issue and can be regarded as part of passive ECM (electronic counter measure). Reduction of RCS is basically made by multilayer coating the surface of the target by lossy dielectrics. In this case, boundary condition which is satisfied on the surface of target can be modelled by IBC (impedance boundary ...

Journal of Optics, 2023
Abstract Integrated meta-devices are the need of modern stealth application systems and have recently received a great deal of attention. Most studies have concentrated on the physics and structural design of planar metasurfaces, while conformal design that is suitable for arbitrarily curved surfaces has been rarely discussed.

Theoretical Background for the Computation of Radar Cross-Section (RCS) Using NEC
2020The entire theoretical framework of NEC starting from the definition of integral equations to the solution of matrix equation is briefly introduced in this chapter. The basis functions used for representing the unknown current densities and the weight functions used for testing are also described in detail.

On the radar cross section (RCS) prediction of vehicles moving on the ground
AIP Conference Proceedings, 2014As readers should be aware, Radar Cross Section depends on the factors such as: Wave frequency and polarization, Target dimension, angle of ray incidence, Target’s material and covering, Type of radar system as monostatic or bistatic, space in which contains target and propagating waves, and etc.

An investigation of the RCS (radar cross section) computation of grid cavities
AIP Conference Proceedings, 2014In this paper, the aperture of a cavity is covered by a metallic grid net. This metallic grid is to reduce RCS deduced by impinging radar ray on the aperture. A radar ray incident on a grid net installed on a cavity may create six types of propagation. 1-Incident rays entering inside the cavity and backscattered from it.2-Incidebnt rays on the grid net

Study on Cylinder's Surface Current Density and Radar Cross Section (RCS) Resonance
2013 International Conference on Information Technology and Applications, 2013Perfect electric conductive cylinder's scattering is a typical 2-dimensional scattering and has accurate solution which is very helpful in study of conductor's surface wave, crawling wave and is often used for validation of computational algorithm. The surface currency density's magnitude and phase's distribution over the profile are studied and the ...

Radar Cross Section (RCS) Measurements
2013The radar cross section (RCS) is a critical parameter that describes the electromagnetic wave - target interaction. Its accurate prediction has long been a hot research and engineering topic. Today, RCS prediction of real targets is achieved via either numerical simulations or measurements. Here, indoor RCS measurements are reviewed in a tutorial.
